The Boo-Stro is an immersive companion restaurant to The Ghosts of Hidden Side. Much like how Disneyland's Blue Bayou Restaurant functions within the Pirates of the Caribbean attraction, it is designed as a place where the food and the atmosphere is the show.

The restaurant is housed within a rotting Victorian greenhouse which seamlessly blends in with the mansion gardens seen in the outside queue and the graveyard section within the attraction itself. The greenhouse setting allows the world of the restaurant to fit within the interior and exterior worlds of the attraction itself without being too obtrusive or attention-grabbing. In the same vein as the Blue Bayou Restaurant in Disneyland and its counterparts in other Disney parks, the attraction-facing side of The Boo-stro is the patio dining area of the greenhouse. Here, diners can view the graveyard show scene of the attraction through one-way glass windows. Not only that this adds to the fun and ghoulishly delightful atmosphere of the restaurant, but it also gives diners a sneak peek of the attraction itself and a taste of things to come, should they ride the attraction after dining.

In addition to a sneak peek into the graveyard show scene, diners within The Boo-stro are encouraged to interact with the attraction itself through the Spectral Analyzer tablets on their tables. In lieu of normal "waiting-time games" usually found on placemats, this fun, family-oriented activity of designing ghosts allows diners to already be involved in the story of The Ghosts of Hidden Side by creating the spooks they themselves would encounter in the ride. These guest-designed ghosts would then "manifest" in the greenhouse through cleverly-hidden screens in the restaurant's glass ceiling before escaping to the graveyard.
